Dear cluster users,

GPU sharding is now available on the OMNI cluster.
GPU sharding enables the parallel use of a GPU by multiple Slurm jobs, this allows a more efficient use of our GPU resources.
Please check if the use of GPU Sharding is feasible for your computations.

More information is available on our website:
